Twitter's new encrypted DM system stores your private key material on Twitter-owned services, protected with nothing more than a 4-digit PIN. If hostile, or if legally compelled to, Twitter could easily decrypt all your messages. It's also MITMable and doesn't secure metadata. Use Signal.

@mjg59 does signal works if your android doesn't have any mobile SIM card ? (i.e. solely over WiFi)

@PypeBros yes, although you do need an available phone number for initial registration it doesn't need to be associated with the device you're running Signal on
